Sahih Bukhari | Volume 7 | Hadith Number 116

Narrated by 'Abdullah bin 'Umar
The Prophet said, "Everyone of you is a guardian and everyone of you is responsible (for his wards). A ruler is a guardian and is responsible(for his subjects); a man is a guardian of his family and responsible (for them); a wife is a guardian of her husband's house and she is responsible (for it), a slave is a guardian of his master's property and is responsible (for that). Beware! All of you are guardians and are responsible (for your wards)."
